Cleome plant named ‘Robspimer’

ABSTRACT

A new and distinct cultivar of  Cleome  plant named ‘Robspimer’, characterized by its upright and compact plant habit; large inflorescences with numerous flowers; purple violet-colored flowers; and tolerance to high temperatures.

Botanical classification/cultivar designation: Cleome hasslerana cultivar Robspimer.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Cleome plant, botanically known as Cleome hasslerana, and hereinafter referred to by the name ‘Robspimer’.

The new Cleome is a product of a planned breeding program conducted by the Inventor in Grain Valley, Mo. The objective of the breeding program was to develop new consistently compact Cleome cultivars.

The new cultivar originated from a cross-pollination made by the Inventor in 2001 of two unknown selections of Cleome hasslerana, not patented. The cultivar Robspimer was discovered and selected by the Inventor in July, 2002 as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Grain Valley, Mo.

Asexual reproduction of the new Cleome by tip cuttings at Grain Valley, Mo. since 2002, has shown that the unique features of this new Cleome are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Robspimer’. These characteristics in combination distinguish ‘Robspimer’ as a new and distinct cultivar:

-   -   1. Upright and compact plant habit.     -   2. Large inflorescences with numerous flowers.     -   3. Purple violet-colored flowers.     -   4. High temperature tolerant.

Plants of the new Cleome can be compared to plants of the parental selections. Compared to plants of the parental selections, plants of the new Cleome are more compact.

Plants of the new Cleome can be compared to plants of the seed-propagated Cleome Queen series, not patented. Compared to plants of the Queen Series, plants of the new Cleome are more compact and have larger inflorescences.

Plants of the new Cleome can also be compared to plants of the seed-propagated Cleome Sparkler series, not patented. Compared to plants of the Sparkler Series, plants of the new Cleome are more uniform in plant growth habit and flower coloration.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Cleome, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Cleome.

The photograph at the bottom of the sheet comprises a side perspective view of typical plants of ‘Robspimer’.

The photograph at the top of the sheet is a close-up view of a typical inflorescence of ‘Robspimer’.

DETAILED BOTANICAL DESCRIPTION

The new Cleome has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity, without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown in Grain Valley, Mo. in an outdoor nursery during the summer and under commercial production practices. During the day, temperatures averaged 32° C. and night temperatures averaged 24° C. Plants were about five months old when the photographs and description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
